Poll backs EU vote.

Another opinion poll has backed a referendum on Britain's future in the E.U.

56% of people questioned by You Gov wanted to be given a vote on 'whether or not Britain remains a member of the European Union.'

71% said they don't trust politicians to work for Britain's interests.

The poll also showed that only 28% of voters oppose a referendum.

1,474 voters took part in the poll last week.
